If motorized boats had been invented in ancient times, The Odyssey would've lasted only 10 days, and Odysseus could have escaped Charybdis with one perfectly timed heel-side front flip. Imagine what might have been with today's Groupon to Las Vegas Boat Harbor in Boulder City. Choose from the following options:

• For $69, you get a two-hour WaveRunner rental (a $140 value).
• For $99, you get a four-hour pontoon-boat rental (a $200 value).
For $159, you get a four-hour rental of a speedboat and a wakeboard (a $320 value).

Owned and operated by the Gripentog family since 1957, Las Vegas Boat Harbor sparks aquatic adventures on the waves of Lake Mead with boat and jet-ski rentals. Up to two joyriders enjoy a couple of hours on the ripple-skating back of a WaveRunner, and six may pile into a speedboat for four hours of wakeboarding and white-whale chasing. Pontoon boats can transport up to 10 passengers to nearby locales such as Hoover Dam and Cathedral Rock or simply explore the man-made lake’s multitudinous inlets and coves, surrounded by 550 miles of breathtaking Mojave Desert shoreline. Guests who drop anchor during their watery sojourn can spend the afternoon supping on lunches packed at home, picked up at the Harbor House Café, or stolen from passing schools of fish, and the marina store supplies any last-minute boating and fishing supplies.
